FIG. 8 is a schematic perspective view of the light source module 20, the bracket 200, and the power supply socket 300 facing the front side in the assembled state. FIG. 9 is a schematic perspective view facing the rear side of the assembled state of the light source module 20, the bracket 200, and the power supply socket 300. 8 and 9 show the mounting portion 220 side when cut along the broken line A shown in FIG.

  The power supply socket 300 has a substantially L shape in which an insertion portion 310b protrudes below the flat plate portion 310a, and a power supply terminal 340 and a biasing arm 350 protrude from the side of the flat plate portion 310a. Therefore, as shown in FIGS. 8 and 9, the power supply socket 300 can supply power to the semiconductor light emitting element 22 from a position that does not block the irradiation light of the semiconductor light emitting element 22 while being fixed to the bracket 200.

  In addition, in a state where the power supply socket 300 is fixed to the mounting portion 220, the first left contact surface 332 of the flat plate portion 310 a contacts the first left position restriction surface 232 of the engagement groove 224. Further, the second left contact surface 334 of the lance portion 320 contacts the second left position regulating surface 234 of the wide portion 224a. Further, the right contact surface 330 of the insertion portion 310b contacts the right position regulating surface 230 of the engagement groove 224.

In addition, the bottom surface of the insertion portion 310b and the bottom surface of the engagement groove 224 are in contact with each other, and the top portion of the position restriction convex portion 228 is in contact with the inner surface of the position restriction concave portion 328. As a result, the power supply socket 300 is positioned in the vertical direction with respect to the mounting portion 220.

  With the above-described configuration, the power supply socket 300 is positioned with respect to the mounting portion 220 in the front-rear direction, the left-right direction, and the vertical direction, so that the connection of the power supply terminal 340 to the electrode 24 is ensured.

  Further, when the power supply socket 300 is inserted into the engagement groove 224, a pressing force is generated by which the power supply terminal 340 presses the electrode 24 toward the mounting portion 220. Thereby, connection to the electrode 24 of the electric power feeding terminal 340 becomes more reliable. Further, the light source module 20 is more securely fixed to the mounting portion 220 by the pressing force.

  Furthermore, a pressing force that urges the light source module 20 in the direction of the mounting portion 220 is generated in the urging arm 350 by the insertion of the power supply socket 300 into the engagement groove 224. The urging arm 350 urges the light source module 20 in the direction of the mounting portion 220 by this pressing force. Thereby, the light source module 20 is more reliably fixed to the mounting portion 220. In particular, in this embodiment, since the power supply terminal 340 and the urging arm 350 press the four corners of the substrate 26 of the light source module 20, the light source module 20 is more reliably fixed to the mounting portion 220.

The bracket 200 and the power supply socket 300 are positioned so that 24 and the power supply terminal 340 are in physical contact. Therefore, the number of parts in the assembly structure of the light source module 20 can be reduced while maintaining the reliability of power supply to the light source module. Further, as a result of the reduction in the number of parts in the assembly structure of the light source module, the assembly man-hour is reduced, the manufacturing process of the vehicular lamp 10 is simplified, and the manufacturing cost is reduced.

  Further, in the vehicular lamp 10 of the present embodiment, the bracket 200 has the engagement groove 224, and the power supply terminal 340 is connected to the electrode 24 when the power supply socket 300 is inserted into the engagement groove 224 and fixed to the bracket 200. Is pressed in the direction of the mounting portion 220. Therefore, the electrode 24 and the power supply terminal 340 are more reliably connected, and as a result, the effect that the reliability of power supply to the light source module 20 is further improved is obtained. In addition, when the light source module 20 is displaced, a desired light distribution pattern cannot be obtained. Therefore, reliable fixing of the light source module is required. On the other hand, according to the configuration of the present embodiment, the light source module 20 is urged against the mounting portion 220 by the pressing of the electrode 24 by the power supply terminal 340, so that the light source module 20 is more securely fixed to the mounting portion 220.

At this time, a pressing force for biasing the light source module 20 to the mounting portion 220 is generated. Thereby, fixation to the mounting part 220 of the light source module 20 can be made still more reliable.

  Moreover, in the vehicular lamp 10 of the present embodiment, since the assembly direction of the power supply socket 300 to the mounting portion 220 is one direction, the assembly work is facilitated. As a result, an effect that the manufacturing process of the vehicular lamp 10 is further simplified can be obtained.
